For the past few years I've been hosting book swaps for my son and his friends. It's an inexpensive way for us to find new books to add to our home library. Nevertheless, the books are in the community language.
We sent them a French/English Dr. Seuss bilingual book with a short note from little one; and she and her son sent us a children's book in Spanish with a sweet note.
Take a look at your friends and family living in another state or country and swap books with them. If you don't ask, you'll never know!
Please note that this is not to be confused with a children's book exchange type of chain/pyramid that I've seen circulating on social media.
Happy book swapping!
